    This sample demonstrates a custom <a>RotatingTool</a> which allows the user to rotate many selected objects at once.
    It is defined in its own file, as <a href="RotateMultipleTool.js">RotateMultipleTool.js</a>.
  </p>
  <p>
    Hold down the control key in order to rotate each selected node individually, rather than all of them collectively.
